CALENDAR.

SPECIFICATION forming part of Letters Patent No. 476,462, dated June 7, 1892.

Application filed April 5, 1892. Serial No. 427,962. (No model.)

To all whom it may concern.-

Be it known that I, Join: HOCHHEIMER, a citizen of the United States, residing at Hamilton, in the countyof Butler and State of Ohio, have invented certain new and useful Improvements in Calendars; andIdo hereby declare thefollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improvement in calendars; and it consists in the construction and arrangement of parts more fully hereinafter described, and definitely pointed out in the claims.

The object of this invention is the provision of an improved perpetual calendar constructed and arranged for use in connection with inkstands or other fixtures for library or Ofiice, and, further, in the peculiar formation and arrangement of parts, resulting in the production of an exceedingly simple, durable, and inexpensive device of the nature above indicated. This object I attain by the construction illustrated in the accompanying drawings, wherein like letters of reference indicate corresponding parts in the several views, and in which Figure 1 is a front elevation of the improvement. Fig. 2 is a longitudinal section showing the inner cylinder partly in elevation, with its upper portion broken away, and a variation in the tabulations on the respective cylinders; and Fig. 3 is a detail perspective View of the hub and seat.

In the drawings the reference-letter A indicates the base of an inkstand, and B and B the ink wells or bottles located on opposite ends of the base, which also constitute supports or standards. The inner faces of the wells B B have vertical grooves Z) therein, having angular seats formed at their lower ends and open upper ends. Between the supports or wells 13 and B is a cylinder 0, having hubs or stub-axles c at its ends formed of a hexagon shape or other angular contour to fit closely within the grooves b and coincide with the seats at the base thereof. This cylinder O is of a length to occupy the entire space between the supports and has surrounding the same a superimposed transparent cylinder or cylindrical shell D, formed of glass or other analogous material. The cylindrical shell is fitted over the cylinder 0 in a manner to allow the same independent rotation,

its length being equal the length of the inner cylinder,thereby causing its edges to abut or engage the vertical side walls of the support, by which means all longitudinal movements are prevented.

The calendar tabulations are of the nature commonly known as the perpetual, and are so arranged that the correct dates of each month of the year, days of the current months, and week-day of any month of any year of a given period may be quickly found with but little trouble. To this end I arrange the names of the months on the left-hand side of the inner cylinder in horizontal lines, as shown, and on the opposite end of this inner cylinder are arranged the numbers indicating the days of the months, while on the inner face of the glass cylindrical shell midway its length and at a point between the indications on the inner cylinder are enumerated the tabulations or characters containing the years of a century, preferably from 1 to 100, which figures are placed in horizontal columns around the entire cylinders in an order well known in the art for ascertaining the date of any given period. At the righthand side of the century characters and on.

the inner face of the cylindrical shell are placed the necessary letters indicating the days of the week, there being a day allotted to each horizontal column of the century numerals or indications. By this arrangement of-characters and numerals it can be readily ascertained on what day of the week any particular day of the month came or comes at any period during the century.

In Fig. 2 I have shown an arrangement of the characters on the cylinder somewhat changed, so that the months week-day indications and days of the month may be adjacent to each other. This form may be desirable for office use.

By constructing the cylinders with a transparent or glass cylindrical shell or jacket movably secured and rotatable independent of the cylinder and at the same time carrying on its inner face the above-mentioned numerals I am enabled to readily change the position of the indications relative to each other, preserving the lettering or figuring but at all times exposing the same. Then it is desired to turn the inner cylinder, the calendar is removed, releasing the hubs c from the sockets or grooves Z). After turning the inner cylinder to the proper position and again inserting the hubs in their sockets, where they are prevented from rotation, the calendar is again in position for proper use.

The glass cylindrical shell may be readily cleaned, thereby preserving the indications on the cylinders and preventing the same from becoming soiled or smirched with ink, as would be the case were the indications exposed.

The subject matter, including an inner member carrying calendar tabulations and an outer member having a transparent exposingface and carrying calendar tabulations, I have made the subject-matter of a concurrent application, Serial No. 427,963, filed on even date herewith.

It is to be understood that I do not limit myself to the glass wells in combination with the cylinder, for it is apparent that any form of support may be substituted therefor. I am further aware that many minor changes in the construction and arrangement of the parts of my device can be made and substituted for those herein shown and described without in the least departing from the nature and principle of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a calendar, the combination, with an inner cylinder containing calendar tabulations, of an outer transparent cylinder moun ted thereon and free to rotate independently thereof, and supports for the cylinders, sub stantially as described.

2. In a calendar, the combination, with a cylinder having oalen dar tabulations thereon,

of an outer transparent cylinder carrying calendar tabulations on its inner face, and supports for the cylinders, substantially as described.

3. In a calendar, the combination, with an inner cylinder having calendar tabulations thereon, of an outer cylindrical sheath or shell formed of transparent material and having calendar tabulations on its inner face, supports for the cylinder, and means on the supports for preventing the rotation of the cylinder, substantially as described.

4. In a calendar, the combination, with a base, of two ink-wells arranged at opposite ends thereof, seats formed in the wells, a cylinder located between the wells, hubs on the cylinder engaging the seats, calendar tabulations on the cylinder, and an independent movable cylindrical shell on the cylinder formed of transparent material and carrying tabulated indicating-marks, substantially as described.

5. In a calendar, the combination,with a cylinder having calendar tabulations thereon, of an outer transparent cylindrical shell loosely fitted on the cylinder, and supports for the cylinder, arranged to engage the ends of the cylinder and shell, substantially as 'de-
